网站部署好后浏览https提示不安全,没出现绿色小锁怎么办?

访问网站后,按f12,浏览器提示:

Mixed Content: The page at 'https://www.dushilianren.cn/'' was loaded over HTTPS, but requested an insecure image 'http://www.dushilianren.cn/uploads/2022/12/3.png'. This content

原因是在https页面中，如果调用了http资源，那么浏览器就会抛出一些错误,

解决办法:在header中加入 Upgrade-Insecure-Requests,会告诉浏览器可以把所属本站的所有 http 连接升级为 https 连接,外站请求保持默认;

添加header方法:

1.iis7

        或直接在网站根目录web.config中定义

 <?xml version="1.0" encoding="UTF-8"?>   
      <configuration>
         <system.webServer>
           <httpProtocol>
           <customHeaders>
            <add name="Content-Security-Policy" value="upgrade-insecure-requests" />
           </customHeaders>
         </httpProtocol>
        </system.webServer> 
        </configuration>

2.apache

    可直接在网站根目录.htaccess中定义

 <IFModule mod_headers.c>     
     Header add Content-Security-Policy upgrade-insecure-requests
 </IFModule>

3. nginx

        server {
            listen        80;
            server_name   (myservername);
            add_header Content-Security-Policy "upgrade-insecure-requests";
            location / {    
                proxy_pass         http://localhost:5000;
            }
        }
